Is Alzheimer Disease an Exaggerated Aging Process?
Whether Alzheimer disease (AD) represents exaggerated aging rather than a disease is controversial. Data about the effects of normal aging on the human brain are essential for clarifying this issue; however, whether coherent common patterns of regional morphologic brain changes emerge in the normal aged brain is unclear. Clarification of regional morphologic changes in the brain associated with normal aging and AD was sought using MR imaging.
